IMPROVEMENT IN MACHINES FOR STIFFENING NETTING FOR BONNET-FRAMES,&c.

Specification forming part of Letters Patent No. 135,730, dated February 11, 1873.

To all wZom it mag concern:

Beit known that I, PETER 0.RrTcHIE, of the city, county, and State of New York, have invented a new and useful Improvement in Machine for stiffening Mosquito-Net, of which the following is a specification:

Figure 1 is a detail vertical longitudinal section of my improved machine. Fig. 2 is a detail cross-section of the same taken through the line 00 m, Fig. 1. v

Similar letters of reference indicate corresponding parts.

The invention consists in the improvement of machines for stiifenin g mosquito-nettin g, as hereinafter fully described.

Arepresents the frame-work of my improved machine, which may be made of any desired length, and of a Width equal to the breadth of the material to be operated upon. The top bars of the frame A are provided with small hooks a, upon which the edges of the mos quito-net or foundation B are hooked, as shown in Figs. 1 and 2. O is a box or trough, in which the st iflening-mixture is placed, and which slides back and forth in ways in the frame A, the friction being relieved by small wheels or rollers. D is a shaft or-roller, the journals of which revolve in bearings attached to the middle part of the ends of the box or trough O. The roller D is covered with sev-' eral thicknesses of a coarse cloth which takes up the stiEening-mixture from the box or trough O and transfers it to the mosquito-net or foundation B as the said box (J is drawn back and forth beneath it. To the journals of the roller D are attached gear-wheels E, the teeth of which meshinto the rack-teeth F attached to the top rails of the frame A, so that the roller D may be revolved to apply the stiffening-mixture to the mosquito-net or foundation by the movement of the box or trough C. To the journals of the roller D are pivoted the ends of a bail, G, to the arms of which is attached a bar or scraper, H, in such a position as to remove the surplus stiffening-mixture that may be raised by the roller D, and thus prevent more than the proper amount of said mixture from being applied to the mosquitonet or foundation. As the direction of the box or trough O is changed the scraper G H must be shifted so as to always be upon the side of the roller D that is moving upward. The box or trough 0 maybe moved back and forth by ropes or chains attached to the box or trough, and which pass around guide-pulleys and around a shaft or drum, to which motion may be given by a crank or any conveir ient power.

If desired, the box or trough may be moved back and forth by a swiveled screw. The stiffcning-mixture maybe evened, the surplus removed, and the meshes of the net or foundation kept open by means of a brush and sponge.

Having thus described my invention, I claim as new and desire to secure by Letters Patcut- The net-frame A having rack F on the lower side, the cloth-covered roller D provided with the pinions E E on its journals, and the movable trough 0 having bearings to receive said journals, all arranged and applied together, as and for the purpose described.
